- Brands: Permatex Ultra Grey, AC Delco, Hondabond, John Deere, Toyota, AISIN, Permatex Right Stuff, Yamalube, MOPAR, Loctite, Pro Seal, Versachem, JB Weld. Does it matter how you apply the gasket maker? Should you wait 10 minutes to allow the RTV to skin over? Let’s find out! Gasket makers also compared for adhesive and cohesive performance on plastic and metal, maximum pressure using a metal clamshell assembly, effectiveness at curing under ideal conditions and chemical resistance. I purchased all the RTV gasket makers and the supplies used for the testing to ensure fair and unbiased reviews. So, thank you for supporting the channel!

Don't know if you realise this, but for people like me this is peak entertainment. After 10+ years watching yt regularly, this is one of my top favourite channels, and I await every weekly video. Keep up this amazing work. And on the side note - these results from sealant testing were quite surprising for me.
Glad you enjoy it!
Ummmm, dude... Todd has 2.61 million subscribers.... a vast majority of them find this stuff "Peak Entertainment".... so honestly, I believe Todd realizes this....
@@additudeobx alright dude 😅👍
You like torque test channel too? It’s good stuff
I agree with you. I especially enjoy the "tempo" of the videos. He's machine-gunning through his projects, yet...doesn't skip anything. Imagine that! 100 % accuracy on full auto
Before I buy something I usually check if you made a video covering how good the product actually is. I can't thank you enough for that.
Thank you very much! This means a lot to me!
Absolutely
Haha, I've spent many times standing in the aisle at a hardware store seeing if and what PF has said before I make a choice! 😄
Same
💯
As a Honda technician of 13 years with a surplus of Hondabond, I'm happy to see it in the top 3. I'm impressed by how well it holds up sealing engine parts such as timing covers and oil pans with so much change in temperature. It's pretty special stuff I even use it for small stuff around the house.
Thanks for sharing.
I work with other brand of cars, but we go to the Honda dealer to buy Hondabond…. 🫣🫣
LOL.....surplus is always the best.
Toyota here...that stuff works AWESOME.....but i got to check out that MOPAR stuff if I run out of toyota......shocked!!!!!!!
I have used 3m weatherstrip adhesive in the past too...that crap is Crazy good.
I also work on Toyotas and have a surplus of the Toyota gasket maker. Stuff is awesome.
Can i use hondabond for sealing coolant surfaces?
One note... The AC Delco is an anaerobic sealant, which is made to seal precision machined surfaces, like transmission cases. To see it's true capability, you need to test it with a precision machined surface. That's why it's a thin gel, so it can seep into microscopic scratches to prevent leakage. Also, it only harden in the absence of air (hence the name, anaerobic), which is the condition is machined surfaces.
No. Any of these sealants can seal machined surfaces. I build computers and the thermal fluid between the machined surface of a processor and the heat sink is a paste. A 1" by 1" surface that must have complete thermal contact or the processor will overheat. Silver thermal paste has been the industry standard for 20+ years. No "gel" required to seep into microscopic spaces. (lol)
You are lying or have no idea what you are talking about. Gel doesn't creep into microscopic spaces. Molecules of whatever sealing agent is being used will be forced into the spaces when pressure is applied.
@@contumelious-8440 you build computers, I build cars. You have no clue.
@@aaronbritt2025 how did you draw this conclusion? An old timer told you that? Just curious. Lol
@@idontno0 I AM an old timer. I know the difference between RTV and anaerobic sealants. Been doing this for 35 years.
@@aaronbritt2025, you're wasting your time with these keyboard warriors. That ac delco stuff is the best thing going for anything to do with hydraulics, the beauty of the product is lost in this video. It is designed to cure only in the joints, any sealant that oozes out of the joint will mix harmlessly with the oil, unlike a rtv which will create lumps that will cause all sorts of trouble with valve bodies. It is simply a case of the wrong application for the product in this video.
An oil filter test would be awesome. Too many comparison videos I've seen are counting pleats with no measurements of filtering capability, oil flow restriction, or some way to test if a 15000 mile filter is any better than a 5000 mile filter. Thanks for keeping up the good work.
I'd love to see an oil filter test. I've taken to buying the car manufacturer oil filters in bulk (Toyota and Mazda), which certainly seem to be high quality, and even provide lubricant on the rubber seal. But over the years I've bought various different "premium" brands, but I don't really know if I'm wasting my money or not.
He has tested oil filters in the past. Seems like a long time ago, tho.
Be VERY skeptical about the "testing" on RUclips channels. I've owned Fords for 40 years, and only NAPA or Motorcraft get the nod, because of their long standing relationship with Ford Motor Co.
Hell yah I’d love to see an oil filter comparison test between top brands like purolator, K&N, Wix, etc.
I agree. Just counting pleats doesn't really say much. A true test would include flow restrictions, flow filtering, filtering size, and so on both when new and after 5k miles use.
I am a car mechanic. And i see all sorts of brands and also take the filters apart after replacing them. The only realy bad thing i see is when filters have been on the car for way to long. I seen filters fall apart when i touch them. Other than that we use mostly purflux filters wich are realy good. I personaly use mann filters. Because i think they are Just built slightly better. Bosch is also fine. We have a budget brand here in the netherlands called nipparts. And i think the steel used on those filters is to weak. As my filter splitter goes trough it without any problem. The filter itself is smaller than any other brand.
The consistency of quality with these videos is insane also seeing how the videos(testing methods improved) and also the confidence in your voice has grown since the older videos which is great, these videos always interest me even if it’s something I don’t need I’ll still watch
Thank you very much!! This means a lot to me!
@@ProjectFarm You earned every letter of it!
Love this channel!!
@@ProjectFarm is the user ProjectFarm2 a bot or really a part of your channel?
@@ProjectFarm Hey could you do a video on the best 3 gallon compressor also comparing oil free compressors to old fashion gas.
Over 20 years ago I worked at a dealership. My manager was a former mechanic and swore by Mopar gasket maker. Very neat to see it do so well in the testing.
Thanks for sharing.
Jimmy I remember my dad using that stuff to pull pranks on people. It was powerful
Mo power!
Thanks! I ran across your tests on the jumpstart power packs after seeing all the various brands on Amazon and trying to figure out which were good/junk which probably saved me more than I'm currently donating but will send more as I watch your testing. You have an incredible knack in fabricating your tests and am in awe of those as much as the videos! Keep up the great work!
Thanks for supporting the channel! I really appreciate it!
The one test you missed, may be arguably an important one: Heating and cooling cycles. I.e. heat with torch allow to cool and do this 5 times then compare the pressure test. This is a very important test because most gaskets get heated and cooled every time the engine runs. Also the head from the engine may actually help cure the gasket!!!
Thanks for sharing,
This is a great point.
@@DavidDavyDavidson Heat does not cure RTV. Moisture does.
@@satamanschmidt3428 That's correct and RTV stands for "Room Temperature Vulcanization".
Nah that is silly since it will not have any heating and cooling cycles before it needs to perform irl.
An important, variable missing is how these sealants react with hot and cold cycles. Also sealants like the Yamalube and AC Delco are designed specifically for very thin, spreading on machine surfaces that expand and contract very quickly, such as a motorcycle case halves. Different sealants for different applications. Still a great test and video though, keep up the great work.
Yep, the Loctite 518 is I think a lot like the AC Delco. There are countless special sealants for every specific task...
Hondabond is awesome.
Forgot how awesome it is , because I haven't messed with a bike in 20yrs.
Anyways I remembered that stuff as I was doing a VW vr6 timing chain job and couldn't have used a better product.
This was my thought as well. Any gasket like this is going to get hot and cold a lot, which could easily affect the pressure. I wonder if the AC Delco product could possibly have relied on it heating up to temperature to fully cure, as well as some of the others to fully cure in the center.
Thanks, will do!
I was hoping to see this too!
Engine builder here. Permatex the right stuff in black is our bread winner
Thanks for the feedback.
From years working as a tech at a Dodge Ram Chrysler Jeep dealership I remember fellow technicians talking about how the Mopar RTV was the best in the industry but I figured it was us just backing our brand. Happy to see our thoughts were on point. Never had a problem with it. I remember always being amazed at how all those diffs never leaked after a service. I was Chevrolet before Mopar so I was always used to having gaskets on everything so it always seemed like some kind of sorcery when I buttoned up a diff on a Grand Cherokee using nothing but Mopar RTV and it didn't come back. Just one of the many reasons I still drive Mopar to this day. I've owned a couple of Jeeps, a couple of Dodges, and even a couple of Chryslers, ans and I've loved every single one. I still remember the first Prowler, Crossfire, and Viper I drove as a service writer. Chrysler Corp was always the company that was willing to do something different. Very concerned about the current direction though. Ditching the HEMI has me pondering a Toyota to replace my current RAM with I love dearly but is creeping up on 12 years old.
Thanks for sharing.
That mopar RTV never let me down when I was a dealership tech, its still the only RTV I'll use today. That AC Delco stuff is really good on machined surfaces.
Thanks for the feedback.
That Ac Delco sealant appears to be the same stuff as either Loctite 515 or 518 gasket eliminator.
I agree, I work at a dealer and the Mopar RTV is some of the best stuff.
GM has a great RTV as well. The anaerobic sealant only cures when thin coats are in contact with metal ions and not in contact with air. It's not a gasket maker.
@@fascistpedant758 Yes, Mopar has the same type anaerobic red sealant.
I think one of the most important takeaways from this test, at least for car people, is the resistance to gasoline. High performance cars for example will often find their oil diluted with some gasoline over time. Using a sealant that does not resist gasoline well in general may result in future leaks. I wonder what the difference is between ethanol free gas, E10, and E85. Could be a good test in the future. E85 cars especially have issues with oil dilution. Having an oil and gas resistant RTV for oil pans and other oiling system seals may be pertinent.
Thanks for the suggestion.
Cars don’t use straight gasoline for lubrication in the engine, unless it’s injectors or high pressure fuel pump.
@@repairvehicle your fuel pump uses the gasoline in your tank as a lubricant that’s why you see high failure rates of fuel pumps from people who constantly run past E. So yes cars do use gas as a lubricant and it’s not uncommon for high compression motors to force some gas into the oil in the means of blow by
@@repairvehicle please get help for your comprehension difficulties and for the love of god, don't advise anyone on how to repair a vehicle until you understand how they work.
@@farvatron , learn to read is the first thing you should help yourself first
I've been swearing by Hondabond for years, It's always thought it was way better than prematex. Now I'll give Mopar a shot because of its additional resistance to fuel. Fuel shouldn't be in your oil, but hey, stuff happens. Thanks!
Fuel shouldn't be in your oil unless you drive a certain japanese product with direct injection
@truckguy6.7 Honda And Toyota?
@@h8troodohEarthdreams engine by Honda
@lvsurfcat8584 no kidding.. what's up with all this oil dilution issues, all of a sudden... especially with the Japanese, they seem to have a handle on their engine technologies... hmmm. Especially Honda.. I think it's low resistance ring sets,I betcha...
Same I think he just converted me to a mopar product
Someone that finally pronounces Aisin correctly I salute you good sir.
Thanks!
Your thorough testing methods leave no stone unturned. Very impressive! Manufacturers could learn a lot about product improvements by subscribing to your channel.
Thank you very much!
Really!
The work you put into these videos is almost overwhelming to even watch. Just imagining the time you spend researching, designing and executing them. The editing, the organization and patience, Doing it all the time, over and over. And every video shows how much you love doing it. It's great to see that. And VERY IMPRESSIVE!

I like Permatex # 2 non hardening ; been around since the 70's ; resistant to coolant and lubricants ; Permatex Form-A-Gasket No. 2 Sealant is a slow-drying, non-hardening sealant approved for use in aviation as well as automotive applications.
Thanks for the feedback.
Agreed, used it for decades. I think it's the best stuff for thermostat housings. Never had one leak.
That's what the manual on my big diesels calls for. Can confirm, that stuff is amazing.
Do you have recommendation a better way to get it off?
I like Ac Delco Candy 🍭 good quality 🤣🤣🤣🤣🤣
I use permatex alot ,cleans up with acetone
I don't need any tools but i watch all the videos. The way you test them is too entertaining, never missed a video! Very good job! The Best channel for comparison.
I gotta say it's beyond impressive that PF gets out one of these videos every week! The excellent reviews, empirical tests, and not to mention top notch video and content quality are FAR from easy to do in such a fast and consistent manner. Thanks again Project Farm, great vid as always!🙏
Our pleasure!
So true. You’d never imagine just how much work it takes to produce a video like this, or any video really, until you try doing one yourself and realize how horrible it is.
Seriously how does he do it all in a week ?!
Another real world test, testing real world stuff for real world people 👍👍👍👍
Thank you! I learned a lot on this one!
I buy products based on your tests. Excellent job.
Thanks!
Amazing. Thank you for taking the time to do this now i know what silicone gasket maker i’ll be ordering from now on. Your channel is awesome
Thank you!
As a former mechanic, I use Mopar ATF RTV on any application that calls for RTV silicone. To be clear, I'm not a Mopar fanboi, I just really like that stuff. The ATF RTV seems to be a little thicker out of the tube than the regular Mopar RTV. Very nice to work with.
Thanks for sharing.
I'm shocked the Mopar did the best in this test. Way better than the Permatex, which I expected to do first or second.
Had no clue as a shade tree that there was any difference, will def get the Mopar going forward.
I am a technician at an Alfa Romeo dealership. Since Alfa is a Mopar brand, we of course use Mopar products as they are what is specified in the Alfa repair information. Alfa specifies Mopar Threebond RTV. I'm not sure what the differences are between it and the standard Mopar RTV, except that it is gray instead of black. The Mopar Threebond is very good stuff, I've been very impressed by it.
@@andrewweltlich9065 Threebond makes a lot of the stuff for OE manufacturers. I know they make several flavors of Yamabond and Hondabond. Including Yamabond 4, my favorite anaerobic sealant.
Edit: I really like Threebond thread lock products as well!
Great test but as a former Gm tech I would recommend using the acdelco rtv that’s gray in color over the red. The red is used a lot less commonly and is usually used in machined aluminum surfaces that are torqued together at a much higher pressure than the gray rtv. We always used the gray for valve covers and oil pans which seems to be your intended application test.
The gray should never be torqued inbetween bare metal in my opinion. Stuff never comes off if you have to go back in.
Anaerobic should only be used between 2 machined surfaces as it dries in the absence of air. in these conditions it will never seal
Agree I’m a gm tech and we never use the red stuff. We always use the gray stuff! I think he got the wrong gm rtv. I keep a new tube in my tool box.
anaerobic, you need to squeze oxygen out of it where PF just set it freely
@@contraband1543 You need a sharp scraper to remove it. Also it was a great sealer but now GM has a better sealant that is much worse to get off surfaces.
This test was alot of work! Thanks for the great tests and the honest channel.
I have used the RIGHT STUFF for valve covers and oil pans, never had an issue. Honda Bond for engine cases. Thanks for the video, very informative
Thanks! Glad to hear!
Great video as always! Unfortunately, the AC Delco Gasket Maker is an anaerobic sealant used for transfer cases due to low thermal and bonding pressure needs due to metal-to-metal case halves. It is not an RTV. I'm sure you were surprised by the cherry red color... GM considers their "Engine Sealant" as their RTV gasket maker for oil pans.
PS - I bet Harley Davidson's "High-Performance Sealant-Gray" would be a great one for the next video!
Yes, and being anaerobic the excess material inside an engine case will remain liquid and pass thru the system.
Yep. And it's never going to cure on plastic because it is catalyzed by metallic ions.
This channel is literally one of the best
The amount of dedication and time spent per video is unreal
Thanks so much!
I love that you actually use the suggestions of viewers. This was one of mine. Definitely changed what I use based on it.
Thanks! Thanks for the great suggestion.
The amount of editing required for your videos is insane! Im watching this while waiting for permatex to dry on my boat lower unit. I used Permatex Motoseal, designed for 2 stroke engines
That mopar rtv is what I’ve used on everything, for the price to performance, you can’t beat it. I actually started using originally on Chevy products and got weird looks when I’d pull a new pack out.. but it was the only that that kept them from coming back with more leaks, but after seeing the results you got.. my decision to order the mopar rtv was for the most part always right.
I love all the videos that project farm has made over the years but using the AC Delco in this lineup was kind of an apple to oranges comparison. I work in a GM dealer and use the AC delco gasket maker all the time. It's not supposed to cure like regular silicone and is an incredible product. If it's applied properly it will never leak. Keep up the good work project farm. I love the videos.
Thank you!
I also work in a chevy dealer and the proper silicone is GMS. Anaerobic is primarily designed for gear cases.
@@Ccarter485 the old GM front differential reseal lol.
You, Scotty Kilmer, Eric the Car Guy and Chrissfix are like The Apostles writing a New Testament.
I’m just now watching your RTV video, I was a diesel mechanic for 20 plus years and the best RTV I’ve ever seen was was a gray RTV sold by international (the truck company) at their parts counter. We used it to seal rear covers on 3408 caterpillar engines when doing clutch jobs. It never leaked and it smoked when it touched the regular Autozone bought RTV. I’d like to see that added to your future comparison videos..
Thanks for the suggestion.
I usually use permatex, which we have at my shop as a consumable. When I want something to last, I get TA 31 from Ford. This is the sealant for the power stroke oil pans and I suspect the same sealant you are speaking about in Ford badging. It has been amazing in my use.
The Mopar RTV you used was generally used on oil pans and valve covers. 44 is for oil pans, 41 is for trans work and 46 is for differentials. Mopar ThreeBond would be a closer to match to the others. It's usually used for timing covers and upper pans. Extremely good stuff. As always awesome test.
Waiting for you to get a "projectfarm approved" sticker to sell to manufacturers!
Looks like the Mopar sealant tested here can be used anywhere on the block.
@@chadd587 They can be I suppose, but in dealer world they all have their purposes.
I'd have loved to see an emergency control with RTV silicone caulking. For me, the pressure and solvent tests were the most informative as they are actually testing the purpose of the gaskets. I wouldn't mind an additional episode testing different solvents against various gasket materials including a selection from here.
Thanks foe the suggestion.
I too would be interested in solvent resistance. I rebuild carbs and fuel pumps and have always used Elring Curil T or T2.
Elring is a German brand. I live in the U.K.
I’m not looking for high pressure but longevity a seal that will last for years, quite hard to test but after a week or a month I’m sure it would have failed if it was going to when in constant presence of fuel ie gasoline (in the U.K. it’s know as petrol or its full name petroleum)
Worked at a diesel shop part time. They used clear silicone for everything, the kind in a caulk tube. It was super cheap and supposedly good to 500 degrees
This channel is the best you can find high quality reviews for basically anything. The video log is so large. I specifically searched for this along with you channel and it came up.
Thanks for sharing!
THIS was definitely one of my favorite tests. Thank you so much for all your content. You have replaced Consumer Reports for so many things.
Thank you!
I've used most of these over the years. The Mopar RTV is the one I prefer for my personal vehicles. Mopar actually has multiple formulas of RTV, and the one for transmission pans seems to be the best all-around in my experience.
Thanks for sharing.
You should try molar Three Bond I’d bet you could put a oil pan up let it cure then pull the bolts out and it would be fine for years😂 when I used to have to pull oil pans at dodge for warranty engine work it would literally bend the pan!
@@1SlowCbrr it sounds a little too good to be honest
@@1SlowCbrr might as well just weld the pan on. That stuff is impressively almost irritatingly strong
Mopar is the best silicon. I have a 2003 ram with 300000k never had a leak.
Man you are a legend 🎉
Thanks!!
Another 1st Class video, just chalked full of valuable information for thousands of viewer's who save money by being able to see testing done the right way, no BS. Thank you for doing this video.
Thanks and you are welcome!
I use gasket makers almost every week. It seems to really depend on what the actual item is being sealed. The material makes a big difference. Engine pans and parts all seal differently. I've had just about every brand fail at some point. I do use the permatex 90min pretty often along with Motorcraft. As a mechanic, we don't have the luxury of waiting 2 or 3 days for sealant to dry. As a trick, just like with adhesive tapes, I use a heat gun to heat up the surface of anything being sealed. Heat works really well with 3m adhesive tape also. Keep up the good work!
Thanks, will do! Thanks for sharing.
The anaerobic sealant is really designed for 2 machined surfaces and works best when clamped tightly. It does become hard, when clamped between 2 machined surfaces, and then allows to get hot under normal operating conditions. Most sealers never see these kinds of pressures, and will only be exposed to heat and splashed lubrication.
Agreed, just left a post arguing our case. Otherwise, love this guy!
@@marcoalessandrini4675 indeed, it was still interesting.
RTV silicone isn't designed to work on "metal machines surfaces" it's silicone just like what you can use with a caulking tube. I think everyone is overthinking this and honestly Project Farm should have included generic or major brands as well like General Electric or 3M silicone. But those high purity brands will all perform about the same and they have been proven to work well enough for head and oilpan gaskets so my question is why pay extra for the RTV gasket maker for the toothpaste tube and the funny dye colors for the silicone.
Second argument I just realized is that premade gaskets are made for finely machined surfaces, gasket sealer is certainly designed for suboptimal surfaces otherwise it would not be sold in the form of a paste or resin form.
@Infernal Daedra those silicone brands you're referring to are nothing like rtv! You definitely need to do your research, those silicone brands do not adhere to surfaces nowhere near as good as rtv silicone
Three Bond makes a couple varieties of hondabond, yamabond etc. It's 1104. I've also seen 1194 which may just be a new number, same product. Best stuff I know of.
One of the best channels on RUclips
Thank you very much!
I'm so happy to see you doing 3 samples! Aways improving and listening to feedback, thanks.
You are welcome!
I always appreciate your videos.
One point I'd make is on most engines your sealing sheet metal,Cast iron or aluminum. And you're not looking for structural support but you're looking for a pressure or vacuum seal.
That being said nothing outperforms The Right Stuff for me.Ive been building engines for 30+ yrs and couldn't be happier.
I will give an honorable mention to Mopar ATF sealant,you can immediately submerge it and it never leaks.
No surprise with the MOPAR. It’s all I use in the shop for sealant. On the AC Delco anaerobic sealant, I think the surfaces have to be machined for it to really work, and it takes a while to cure. I remember it being used on transfer cases on GM trucks for their housings.
Thanks for sharing.
yeah alot of our shop customers just swear by the Mopar silicone
A helpful hint: I had a rusty gas tank in a truck dripping bad. I put a sheetrock screw in hole and coated with Permetex Indian head shellac a few times ( on side of highway Emergency repair) .
After two coats No leak ..
It sets up even with gas leaking !
Amazing old school Indian head shellac Brown sticky stuff .
Impressive repair! Thanks or the tip!
I have found that the shellac works well unless around heat
You do a great job. The amount of work and time it takes to do this would put me in the mental ward. Thank you for all you do
Thanks and you are welcome!
Oh wow, I asked you if you could test gasket makers on the LTT Screwdriver test video and you went ahead and done it. Thank you so much, really appreciate it. It's great to know you read our comments and take suggestions if it makes sense to you. Such informative videos. You're the man👍🏾👌🏾
Thanks!
You are by far one of the best channels to watch. I love the rigor that you put into your videos, and I appreciate that you mention when you change out something to make a more pleasant viewing experience.
I would love to see you and Adam Savage get together and do some crazy tests.
Edit: Forgot to ask for what I wanted, I know it would be expensive but I would love to see a video regarding on-demand hot water heaters. Or portable solar panel backs for backpacking/camping.
Thanks! Thanks for the suggestion.
I see these little water heaters in bathrooms in SE Asia and South America.
One of ours is over ten years old and works perfectly.
Cost about $125 new.
One product you missed, that I use all the time, and works really well, is the Permatex Ultra Black Right Stuff. Idk why, but I've always found Black holds up better than gray or any other color.
Thanks for the suggestion.
One of the best videos and tests yet! Thanks for doing the pressure tests I think that was important.
Thanks so much!
No clue what RTV is or what it’s used for but I trust this man. AC Delco should just shut down
I haven’t found any yt like this with so much information I appreciate all your hard work!
Thank you very much!!
Brilliant! 👏👌 Been wondering about how other products compare as I work with adhesives. The AC Delco one should be in its own separate range of tests for that technology ie: Anaerobic gasket compounds (not with RTV Silicones). Anaerobic will only ever cure when air/oxygen is excluded between two "active" metal surfaces, hence why it was completely uncured with the plastic. More active metals will cure faster and to higher shear strength than the inactive ones. That could be another video!!?? 😉
Thanks! Thanks for the suggestion.
Is it just me, or are these test getting better? This is GREAT!!!!!
Thanks!
Awesome video, as always. Anytime JB is involved, it always is at the top for price vs value.
Thanks!
This test showed exactly why not to use silicone on fuel / inlet mainfolds. Also I think the oil pressure tests should be done at engine operating temps.
And spray hot oil all over his shop?
Unnecessarily complicated. Where’s your gasket testing video?

Thanks and you are welcome!
These tests, and your testing jigs are awesome. I can tell you put much thought into your videos. The scripts are always well thought out. Great job, Todd!
Thanks and you are welcome!
The comparison I didn't know I wanted to see! I had high hopes for the deere sealer because I use it so often in my line of work, I might have to start stocking the Mopar stuff
Thanks for sharing.
Yeah the John Deere stuff got really blown out of the water in almost all tests.
A really great testing video on something that I've used a lot of over the years. Excellent as always! Thank you
Thanks and you are welcome!
I am a young medical facility maintenance technician and I frequently am awaiting more of your videos, I almost religiously make my decisions based off of your testing, thankyou PF!
You are welcome!
This was a most useful test on something we tend to just take for granted. I will know to always buy MOPAR gasket maker in the future. Thanks!
Thank you!
Todd, it can't be said enough re: the amazing/thorough job you do, and how effective your tests are i.e. how helpful they are to everyone who watches.
I hope you able to do these for years to come; on into old age where you find yourself testing/comparing: Geritol equivalents and hearing aids. 😁 😄
Loving this channel more & more from every aspect.. Starting with the hard work and effort you put in these videos down to the smallest detail even to using the Imperial system and posting it on the screen as in Metric..
Respect and all the best.
I appreciate that! Thanks!
Idk how you keep making these amazing videos but please keep it up. They are super relevant to the average car guy/mechanic
Thanks, will do!
The AC Delco looks to be the same type of sealant as Loctite 515/518, an anaerobic sealant that requires an activator spray when used on non-metal surfaces or between "non active" metals (brass, stainless steel) as opposed to "active metals" (aluminum or iron). I've used the Loctite equivalent for awhile, but i'm very selective about where and when, and i usually use the activator spray. I use it to seal aluminum motorcycle engine cases and parts, and sometimes like to use it as a gasket dressing. I think it would have done better if things were done a little differently. Great video, the results between RTV's were very surprising! I would be interested in seeing different colors of RTV used in applications where another color would be ideal, to see how different they really are.
Thanks for the suggestion.
Your dedication to making your testing as objective as reasonably possible is amazing!
Thanks!
What great benefits is this man doing for the buying public! Cheers to Project Farm, The Captain of testing. Peace be unto you.
Thanks so much!
Astonishing amount of work, outstanding video as always. The only thing I think would also have been revealing is bringing the test assemblies up to engine temperatures to see how it effects performance. I also would to see the Mopar applied outside of directions since it was a far better performer than the JD.
Video suggestion/idea I would certainly love to see tested:
Best high heat adhesive/sealants/paints.
Sure appreciate what you do.
Thanks and you are welcome! Thanks for the video idea.
Yes, choosing the John Deere brand for that testing was unbelievably asinine.
High heat adhesives/sealants for the win....
Exhaust fixes might be one to consider, although they've been reviewed, I don't think a uniform approach or standard for test types across each method has been used....
Kind of like crimping vs soldering connections and what not..🤦♂️
Great one I was surprised when I had to use this on my car. I bought the Toyota brand from the dealer and have great success and used many times.
Love the content.
Great feedback on the Toyota brand!
I think the AC Delco is supposed to work as a flange sealant similar to Loctite 518. It's an anaerobic sealant while RTV is an aerobic sealant. It is for metal flange surfaces and it is supposed to be applied a bit thinner and fill small gaps. I could be wrong, but that's what it looks like to me. Googling it provided little information, but I'm sure the GM service manual calls for specific use cases.
It's for magnesium transfer cases if I'm not mistaken.
@@Kbl-pu2sc That would probably be an appropriate application. I know for example the NV4500 transmission for Chevy/Dodge used to call for anaerobic sealant on the input shaft tower, steel to steel surfaces with tight tolerance, but later switched to RTV.
Yeah anaerobic sealants are extremely good in their use cases, but none of the tests he did were appropriate for it.
It won't harden on plastic at all and the sheet metal pieces are not flat enough. You'd need a milled or ideally a grinded sealing surface on an alloy or cast iron flange (like an engine cover) to see it perform as it is meant to.
I hope you make good money from these videos. Packed with great content and zero filler. Bravo!
Thanks!
Have been using Hondabond ever since I starting doing my own maintenance, have tried similar RTVs and even the Toyota FIPG, have always gone back to Hondabond for important stuff like oilpans and water pumps.
Loved this video comparison and was fairly confident the Hondabond would do well. This was a great video idea suggestion and flawless testing execution by Project Farm once again!
Thanks!
Except Hondabond was 8/13 for pressure testing, the only test that matters for sealing pressurized parts. One of the WORST that was tested. Other than that, it was great for bonding PVC to metal...
One of my Sunday highlights. Thanks for the videos. Dying for you to test Shell Rotella T6 Heavy Duty Diesel Engine Oil.
Thank you for the video idea!
Having been an engineering technician for the last 26 years I definitely enjoy your channel. I actually envy you the way you explain things and set up your test is impressive!!! and it is easy to see you really enjoy what you were doingKeep up the fine work!!!!
Thanks, will do! Thanks for sharing.
Wow man I love your tests. I know this was a tedious one and messy as well. You’re outstanding most people would’ve given up. I know I would’ve just watching the mess tightening each nut and bolt.
Thank you!
Good test. The Anerobic like the ACDelco is doing just what it's meant to do. It's a non-pressure sealant for cavities that are exposed to oil splashes, drips, etc. We use it on covers for machinery like lathes and mills at work because it seals the oils from leaking, but the covers can still be easily removed for future maintenance. High bond is not desirable in any application where you know you'll be removing the cover in the future.
Thanks!
This was by far the most impressive breakdown of a product I've watched. I do video editing for fun.... That's all.... And basically, I just respect the amount of work that went into this one! I do for all but holy cow this one's got my head spinning. Much respect! Thank you! I learned allot
Thanks so much! Glad to hear you learned a lot!
Great test. Interesting how the strongest “glue” is not necessarily the best sealant. And very interesting how many really need more cure time than instructions say. Thanks for the E10 test! I remember when we used #2 Permatex or Aviation Form-A-Gasket, and it held up to fuels and lubricants, but we used alcohol to clean it off our hands. I steer clear of all gasohol as much as possible. Thanks!👍
Thanks and you are welcome!
I drive to another state to get "blue gas" (no alcohol) because the CEL comes on when I use that E15 crap in my flex-fuel '09 chevy....
I use isopropyl to thin down the Aviation and I still use it and #2!.
@@twistedhillbilly6157 I buy real gas from Farmer’s Supply or another local (Nelson Petroleum) whenever I can. Always run my power equipment and old tractor on alcohol free.
@@lanedexter6303 The only small engines I use anymore are generators and occonsionaly a pressure washer and chainsaw. REAL GAS is not available in CA anywhere as far as I know. I converted all the generators to Propane so no more problems there. I don't have a lot of problems with the 2 strokes probably due to no float bowl and the oil in the gas and the Honda engine on the pressure washer is built a lot better than the China crap but I have had to clean the carb a couple times in 15 years or so.. The Chevy pisses me off because they know about the issue and it's an easy fix but they want me to pay for it. they would rather I HATE GM instead of paying an entry level tech 15 minutes to do the fix....
As a Mopar Parts Manager, this result makes me smile inside :-)
This is an eye opener! The Mopar product surprised me! I had my money on the Toyota product! Thank you!
You are welcome!
This is an awesome video and even applies to my job. Love the stuff you do. Would be excited to see more brand of sealant test like a companion of the three different motorcraft types TA-30 TA-31 AND TA-357.
Thanks and you are welcome! Thanks for the suggestion.
Nicely done! I always struggle to pick which one of these to buy for my needs, and normally all I rely on are the claims on the package, which are often exaggerated.
Great point on the marketing!
I trust this guys methods so much I just skip to the end so he can tell me what to buy every single time.
This video is going to change the types of RTV I use on my projects. Thanks for all the info live the videos!
You are welcome!
I love how much though, effort, and transparency goes into all of your videos. Your channel is one of my favorites and it’s always fun seeing what you test next.
I would be interested to see a video on new vs remanufactured automotive parts. Maybe a couple different types of parts typically remanufactured and see how they perform compared to the new version of those parts. A kill test on them would be cool to see if the remanufactured parts fail sooner than the brand new parts.
This is a great idea!
Thanks! Thanks for the suggestion.
I'm curious how they would perform after a few heat cycles.
I don't consider the stuff dry untill running the vehicle a few times personally.
Also i'd like to see chemical resistance against DEF, antifreeze, transmission fluid, gear oil.
I've mostly used Versachem or Permatex black over the years. Sometimes i'll use the red stuff for higher heat areas.
I tried nearly every product here to seal an intake reed valve on a 2 stroke atv. Every one of them failed the pressure test that you have to do when rebuilding 2 strokes except for Honda bond, as soon as I seen this video I knew Honda was gonna rip up the competition, wasn’t disappointed!
Thanks for sharing.
Your vids are awesome. I think you leave no failure questions other than other products.
Thanks!
